Where Tradition Meets Science — Redefining Modern Wellness

Our Story

Rooted in centuries of Japanese heritage, sericulture once flourished as the art of silk. Today, it stands at a crossroads.

In history, silkworms were treasured as medicine.
Through dedicated research, we uncovered their hidden wealth — a rare source of holistic nutrition.

Known in Japan as “the insect of heaven”, the silkworm now returns in a refined new form, designed for modern living.
